Alkanes are saturated with very strong molecular bonds between particles. This means that alkanes have a high activation energy. Once this amount of energy is overcome, the reaction begins and a chain reaction begins. The amount of energy that is required to break the bonds and begin the reaction is far less than the amount of energy that is given of by the reaction.
This is the complete combustion of Propane gas.
Alkanes and Halogens
When alkanes mix with a halogen, a Substitution reaction occurs as the Hydrogens are replaced with the more electronegative elements such as chlorine. The reaction can continue until all of the Hydrogens are substituted by the halogen.
